单选题 Laura was married for 6 months. Her husband was using drugs. She didn't want her son or her unborn baby to live that way, but she was afraid to ask her husband to leave. She left him a note instead. After reading the note, Laura's husband waited for her to come home and then beat her and her son. Laura had little education and she never had a good paying job. She was ashamed to ask for help from the police, courts or women's shelters. Sometimes her husband was very nice to her. She decided to try harder so her children could have a home and a father. Laura joined a church and told a priest about her problem. But her husband kept using drugs and hurting the family. Finally, she told her husband she loved him, but they should live apart for a while. He beat her again. The priest came over to talk to her. He asked the husband to go out for a while. Laura packed up her things and left home with her son. The next day she lost the baby. Her husband went to jail. Laura got a lot of help from groups that help women who have been beaten.

单选题 Shoes are outer coverings for the foot. They have soles, and most have heels. The upper part of most shoes extend no higher than the ankle. Boots are footwear that reach beyond the ankle. People wear shoes to protect their feet from harsh weather, sharp objects, and uncomfortable surfaces. Shoes are also an important part of people's clothing. As a result, fashion often determines the style of shoes that individuals wear. The desire to be fashionable has led to many unusual shoe styles. In the 1300's, many European men wore shoes called crackowes, which had an extremely long toe. From the 1300's to the 1700's, some European women wore shoes with really thick soles causing walking to be virtually impossible without support. Shoes once worn in the Orient were connected to a stilt (高跷) as high as six inches. Traditionally, most shoes are made of leather. But many other materials are now used. Including canvas, velvet, and synthetic substances such as plastics. Footwear materials and style vary somewhat, depending on climate, custom, or other differences. Farmers in Netherlands often wear heavy wooden shoes that protect their feet from the damp environment while Japanese wear shoes outside their home but prefer soft slippers at home. In fact, people in some regions often wear foot coverings other than shoes. Some wear sandals during the hot summer and switch to warm boots for the cold winter.

单选题 Crocodiles (鳄鱼) lay their eggs and leave them under leaves or sand. Baby crocodiles have special sharp teeth with which to break their way out of the shells. Crocodiles only live where it is hot. They are found in India, Australia, Africa and America. They spend most of their time lying around in the mud or the rivers. The crocodile's long powerful tail is used when the animal is swimming. It is also an excellent weapon, because it can be swung with great speed and force. One blow will knock down a man or even a big animal at once. The crocodile is very well protected against its enemies by the hard bony plates which cover most of its body, but because of the way its neck is formed, it cannot turn its head from side to side and so it can only see in front of itself. The crocodile has its teeth cleaned by the crocodile bird. For its food this bird takes the bits left in the crocodile's mouth. This helps the crocodile, which cannot clean its own teeth, for it cannot move its tongue up and down. With its rows of terrible pointed teeth it seizes its food, which may be a fish, an animal, or even a careless human being, and then holds it below the water until it is drown to death. The long-nosed crocodile is shy and timid and because of this, the people of West Africa where it lives, sometimes catch it for food. Many, many centuries ago there were crocodiles in England. We know this because we have found their bones buried far down in the earth on which London is built. But the Britain of today is too' cold for them to live in. Crocodiles may grow to over thirty feet in length. When they lie floating in the water, they look like floating tree-trunks and it is often impossible to tell that they are there.
